Hybrid tea rose plant named ‘TAN98485’

ABSTRACT

Hybrid tea rose plant having large, silvery-blue, fragrant flowers.

Genus and species: Rosa hybrida.

Varietal denomination: ‘TAN98485’.

SUMMARY OF THE INVENTION

The present invention relates to a new and distinct variety of hybrid tea rose plant named ‘TAN98485’, which was originated by me by crossing two unnamed, unpatented varieties.

BACKGROUND OF THE INVENTION

The primary objective of this breeding was to produce a new rose variety having large, silvery-blue, fragrant flowers.

BRIEF SUMMARY OF THE INVENTION

The objective was substantially achieved, along with other desirable improvements, as evidenced by the following unique combination of characteristics that are outstanding in the new variety and that distinguish it from its parents, as well as from all other varieties of which I am aware:

1. Fragrance;

2. Large flowers; and

3. Bluish petals.

Asexual reproduction of this new variety by budding on Rosa canina rootstock, as performed at Uetersen, Germany, shows that the foregoing and all other characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.

COMPARISON WITH PARENTS

‘TAN98485’ bears blossoms of a lilac color. The female parent has bluish-pink flowers; the male parent has pink flowers.

COMPARISON WITH SIMILAR VARIETY

The variety Mainzer Fastnacht (unpatented) is the most similar variety and is more perfumed than the candidate variety.

BRIEF DESCRIPTION OF THE ILLUSTRATION

The accompanying illustration shows typical specimens of the vegetative growth and flowers of this new variety in different stages of development, depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.
